Description
Technical field
The present invention relates to a kind of earth wire of overhead transmission line, specifically one and be applicable to 110 kilovolts of overhead transmission line anchor support common ground lines.
Background technology
Service area must be protected from the danger of incoming call suddenly by maintenance side at two ends, service area hanging earthing conductor during high pressure overhead power line interruption maintenance.It is illustrated in figure 1 Conventional insulation rod earth wire schematic diagram, the Conventional insulation rod earth wire that 110 kilovolts of overhead transmission lines of present use is by earthing dop 10, insulating bar 6, annealed copper wire 9, spring gib head 400 forms, one end of annealed copper wire 9 connects spring gib head 400, the other end of annealed copper wire 9 connects earthing dop 10, first by earthing dop 10 ground connection during use, then handling insulating bar 6 makes spring gib head 400 hook wire, 9 dozens of back buckles of annealed copper wire are used in insulating bar 6 rear end, complete to install earth connection step, insulating bar 4 is retracted with annealed copper wire 9 during dismounting, spring gib head 400 is made to separate with wire.
The common rod tower hanging line structure of 110 kilovolts of overhead transmission lines is as shown in Fig. 2 to Fig. 6: being illustrated in figure 2 straight line pole circuit line-hanging structure schematic diagram, aerial condutor 300 is straightway, and insulator 200 is suspension insulator, hangs down and puts below the cross-arm being suspended on shaft tower 100；Fig. 3 is corner anchor support exterior angle pendant line structural representation, corner pole is exactly the direction of advance needing to change wire 300, wire 300 is at a certain angle with the cross-arm of shaft tower 100 shape in the horizontal direction, and earth connection needs to be overlapped on side, exterior angle, namely in the outboard wire 300 of insulator 200；Fig. 5 is non-corner anchor support line-hanging structure schematic diagram, Fig. 6 be the A shown in Fig. 5 to partial view, as shown in Figures 5 and 6, wire 300 is the most vertical with the cross-arm of shaft tower 100, and earth connection needs to be overlapped in the outboard wire 300 of insulator 200；Fig. 4 is corner anchor support interior angle pendant line structural representation, and wire 300 is at a certain angle with the cross-arm of shaft tower 100 shape in the horizontal direction, and earth connection needs to be overlapped on interior angle side, namely on the wire 300 outside insulator 200.
Above-mentioned Conventional insulation rod earth wire is limited with insulating bar 6 type of attachment due to spring gib head 400, the U-shaped opening direction of spring gib head 400 cannot adjust (direction of U-shaped opening is parallel with insulating bar axis) with the relative angle of insulating bar, although and applying very convenient in the installing of the side, exterior angle of angle tower on tangent tower, namely can be articulated on the line-hanging structure of the shaft tower 100 shown in Fig. 2, Fig. 3；But its shortcoming is to be difficult to be attached on the wire outside non-corner anchor support insulator 200, more it is difficult to be attached on the wire outside the interior angle side insulator 200 of angle tower, namely it is difficult to be articulated in Fig. 5, on the line-hanging structure of the shaft tower 100 shown in Fig. 6 and Fig. 4, if needing to install by force must by bearing tool (such as: ladder, manned whippletree etc.), staff is made to enter on the wire 300 not having earth connection to protect, hand-held spring gib head 400 is articulated on wire 300, it is also required to during dismounting enter side of wire, bring the biggest difficulty to installing earth connection, substantially prolongs earth connection installing and the time removed, have impact on the operating efficiency of interruption maintenance work and do not meet safety operation requirement.
Meanwhile, this Conventional insulation rod earth wire relies on spring gib head 400 to clamp wire 300, and spring gib head 400 manipulates in high-altitude inconvenience the far-end of handheld terminal, people, and wire 300 clamps difficulty, is not easy to installing and the dismounting of earth connection.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the present invention provides a kind of 110 kilovolts of overhead transmission line anchor support common ground lines so that it is being applicable to 110 kilovolts of overhead transmission line any turriform line-hanging structures, wire clamping simultaneously is reliable, installs and removes conveniently.
The present invention realizes with following technical scheme: a kind of 110 kilovolts of overhead transmission line anchor support common ground lines include gib head, insulating bar and annealed copper wire, and one end of annealed copper wire is arranged on gib head, and the other end connects an earthing dop；The top of gib head is the U-shaped opening of clamping wire；Also including a cross bar, one end of cross bar is fixed on the root of gib head, and the other end installs a regulation support that can rotate around cross bar, and the top of insulating bar is fixed on regulation support；The central authorities of cross bar are provided with screw；Leading screw is fixed with lock dog through screw upper end, the top of lock dog is circular groove, relative with the U-shaped opening of gib head form wire draw-in groove, the side of lock dog is provided with the gathering sill that the middle staight shank with gib head matches and can slide up and down along middle staight shank, the lower end of leading screw connects one end of a flexible axle, the other end of flexible axle connects a turning handle through insulating bar, and turning handle is arranged on the bottom of insulating bar；The wire clamping and locking mechanism that lock dog, leading screw, flexible axle and turning handle are constituted.
The invention has the beneficial effects as follows:
1. regulation support can rotate around the root of gib head, can conveniently adjust the relative angle that gib head is installed with insulating bar, by changing the connected mode of gib head and insulating bar, change Impact direction during gib head mounting wire, the strength conductive form of pulling force, pressure is changed into the conductive form of torsion, so that earth connection goes for the line-hanging structure of various turriform, it is adaptable to 110 kilovolts of any turriforms.
